6 Ways to Protect Yourself against Blue Light Eye Damage

How much time do you spend on a computer every day? What about your smartphone? Tablet? Etc. A 2016 Nielsen Company study found that adults in the United States spend an average of 10 hours and 39 minutes every day looking at one type of digital device or another. This time frame increased by a full hour compared to a similar study the company conducted in 2015.

All digital devices emit something called “blue light,” a low-wavelength, high-energy light that has the potential to damage your eyes in the long run. Although there are other sources of blue light that we are regularly exposed to (the sun also emits blue light), the concern with digital devices is related to their proximity to users and the increasing amount of time they are used. . Children are of particular concern because their developing eyes absorb more blue light than adults, putting them at greater risk of damage.

Blue light itself is not all bad. It can increase alertness and mood, supports cognitive function and memory, and helps regulate the body’s natural sleep cycle (circadian rhythm). But overexposure can lead to things like digital eye strain (computer vision syndrome) and retinal cell damage (which can increase your risk of problems like macular degeneration).

Digital devices play an integral role in our lives, so it’s unrealistic to suggest you avoid them altogether. However, there are a number of things that can be done to help minimize potential problems.
